Professor Tian had a great technique.
He made a skin incision, exposing the spinous process and lamina. The 2 lower vertebrae from the pathological vertebra were also fully visible.
In order to better expose the incision, he needed to cut both sides of the sacrospinalis adjacent to the pathological vertebra and separate them through proximal and distal retraction.
Under normal circumstances, the patient would have around 200 mL of bleeding.
The reason for that was because the surgeon would breach the periosteum in the process of exposing the spinous process and lamina.
However, the surgery today went surprisingly well.
The bleeding was maintained well below 50 mL, and the entire surgical field was exceptionally clean.
Professor Tian was very satisfied with his own technique. He felt that today's surgery would be smooth sailing, and the bleeding volume would probably be capped under 3 liters.
